What is an OSL?

OSL typically stands for 'Optically Stimulated Luminescence,' which is a technique used in geology and archaeology to date the last time mineral grains were exposed to light. OSL specialists work in laboratories to analyze sediments, helping to determine the age of archaeological sites or geological formations. Their job involves sample preparation, lab analysis, and interpreting results for research or environmental projects. These professionals often have backgrounds in earth sciences, physics, or related fields.
